The CEMA Steuersatzlager ACB 41 x 30,5 x 7,7 x 45°/45° is a high-quality headset bearing designed to deliver smooth, precise steering performance on modern bicycles. Built to fit integrated and semi-integrated headset systems that use this popular angular contact bearing size, it helps ensure a tight, play-free connection between fork and frame. The 45°/45° contact angles are a common standard in many road, gravel, and mountain bike headsets, making this bearing a practical replacement option when your original headset starts to feel rough, notchy, or develops play.
CEMA is known for producing durable, low-friction bearings, and this headset bearing is engineered to withstand the constant loads and impacts that occur at the front of the bike. It is suitable for riders who want to refresh an older bike, maintain a high-performance machine, or simply keep steering precise and reliable in all weather conditions. Whether you are a home mechanic or a professional workshop, having a correctly sized, high-quality headset bearing on hand makes servicing easier and extends the life of your frame and fork.
